Application filed February 19, 1913. Serial No. 749,432.

To all whom it may concern:

Be it known that 1,, CHARLES Annals-Rau- DALL, a citizen of the UnitedStates, reading at Boston, in the county of Sufi'olk and State ofMassachusetts, have invented certain new'and useful Improvements inHead- Supports for Telephone-Receivers, of which the following is aspecification.

The present invention relates to improvements in supports and moreparticularly to head supports for telephone receivers, whereby the.telephone receivers may be conveniently held upon the head of theoperator. 7

Head supports for telephone receivers have been provided with a headband having the receivers non-adjustably secured thereto, thereby thereceivers are held upon the head. of the operator by a constant andconsiderable pressure against either or both ears'of the operator. Thisconstant pressure is most annoying, irritating and very injurious. Thereare also other serious objections to such head supports which are wellknown to telephone operators at exchanges, to train despatchers andothers skilled within this art, 7

It is the object of this invention to overcome these serious objectionsand defects, by providing a head support which may be easily and readilyapplied or removed from the head of the operator, with simple andconvenient means for adjustably supporting the telephone receivers, maybe adjusted to and from the head of the operator to any desired positionfor hearing and without contacting the ears of the operator.

A further object of the invention is to provide means for adjustablysupporting the telephone receivers upon a head support whereby thereceivers maybe easily and quickly adjusted and frictionally retained inthe adjusted position.

With the above and other objects in view the invention consists of thenovel features of construction, combination, formatiomand arrangement ofparts as will be hereinafter more fully described and particularlypointed out in the appended claims.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that the right is reserved to any changes,

alterations and modifications to which revention and without departingfrom the same.

The invention will be best understood by reference being had to theaccompanying drawings taken in connection with the following detaileddescription forming part of the specification in which Figure 1, is arear elevation embodying my invention. Fig. 2, is a side elevation of sothat the latter the same. Fig. 3, is a vertical detail section taken onthe line 3-3 of Fig. 1. Fig. 4, is a detail horizontal sectional viewtaken on the line 4-4 of Fig. 1, and Fig. 5, is a detail frontelevation.

Reference now being had to the drawing wherein like and corres ondingparts are designated by like reference characters throughout the severalviews the numeral 1 indicates the head band of an ordinary head supportfor telephone receivers being made of suitable resilient material.Pivotally secured to the extremities of the head band are a'ngularlyextending members or wings 2 which are adapted to rest upon the headbehind the ears of the operator, to help to hold the head band in place.These angular extensions may be of any desired shape and may be adjustedto suit the wearer. The in nor faces of the said extensions are alsoprovidled with soft or yielding cushions or pa 8 3. K

Secured to the outer face of the extremities of the head band by meansof fiat headed screws 4 are L-shaped' bearing supports 5. These supportseach comprise a plate having formed at right anglesthereto a stationarybearing 6 and the opposite end of the said plate is provided with adetachable and adjustable'bearing 7. Mounted within the said bearings 6and 7 are stationary shafts 8 each having pivotally connected thereto anarm or lever 9 and the latter each having adjustably secured theretosuitable telephone receivers 10. The free ends of the said levers 9 haveformed therein vertical elongated slots 11 through whiehextends thethreaded pins 12 carried by the receivers 10. Check nuts 13 are providedupon the threaded pins 12 whereby the re ceivers may adjusted positionin front of the ears of the .operator.

To provide means for frictionally holdcourse may be had within the scopeof the in spirit or sacrificing the efiiciency of the be held in thedesired vertical ing the arms 9 to and from the ears of the operatorwashers 14: made of suitable resilient material are mounted on theshafts 8 between the bearings 6 and 7 and the arms 9. The inner faces ofthese washers are concaved so that when the movable bearings 6 areadjusted upon the shafts 8 by the check nuts 14 the washers will bearagainst each side of the arms 9 thereby frictionally holding the latterin the adjusted position.

The movable bearings 6 are prevented from turning with the arms 9 bymeans of a suitable lug and slot connection. The preferred form of thelug and slot connection is by providing each of the movable bear-. ings6 with a lug extension 15 which is adapted ,to operate within horizontalslots 16 forme'dwithin one end of the plates of the bearing supports 5.

It is obvious from the foregoing that by adjusting the movable bearings6 the washers will yieldingly hold the arms 9 in the adjusted position,with proper pressure and without distortion of parts, thereby permittingthe operator to easily and quickly adjust the receivers to hang normallyclose to the ears without any pressure thereon and may also be moved toand from the head of the'operator to any desired position, withoutremoving the head band. This feature of the invention is of greatimportance and convenience in use, especially when the reproduction atthe receiver is of great volume of tone, ,which isfrequently the casewhen receiving from a nearby station and also when the disturbing noisesfrom induction occur or other annoying and often danerous noises, all ofwhich may be readily and absolutely overcome by the proper adjustment ofthe receivers from the head of the operator.

Having fully described the invention, what I claim as new and desire tosecure by Letters Patent is 1. In a device of the character describedthe combinationwith a head band, supports secured thereto, shaftsmounted within said supports, levers mounted upon said shafts, springwashers carried by the said shafts on each side of the levers, movablebearings for said shafts and means for'moving said ceivers,

bearings substantially as and for the purpose specified.

- 2. In a device of the character described the combination with a headband, of angular extensions carried thereby, L-shaped supports, meansfor securin the supports and extensions to the head and, movablesupports, pins carried by the movable supports and adapted to movewithin slots formed within the L-shaped supports, shafts mounted withinthe said supports, receivers pivotally connected to the said shafts,spring washers carried by the shafts and means for adjusting the movablebearings for the purpose specified.

3. In a head support for telephone receivers, an elastic head band,means for securing said band upon the head, without pressure upon theears, a telephone receiver adjustably attached to the head band, andfrictional means for automatically holding the receiver tightly against,or in light contact. with the ear, or removed the extreme distancepossible from the ear.

4. In a head a head band, means for securing said band upon the head, atelephone receiver secured to the head band, and frictional means forregulating the ressure of the. receiver upon the ear and or holding thereceiver permanently in any desired position.

support for telephone re-.

5. In a head support for telephone receivers, a head band, receiver armssecured to said band, receivers mounted on said arms, and meansinterposed between said band and said arm for regulating the pressure ofthe receivers upon the ears.

6. In a head support for telephone receivers, a head band, receiver armssecured to said band, receivers mounted on said arms, and frictionalmeans interposed between said band and said arms for regulating thepressure of the receivers upon the ears.

In testimony whereof I aflix my signature in presence of two witnesses.
